Deinotherium

Just in case you hadn't seen enough weird prehistoric elephant-like animals today, here is a Deinotherium. Apparently it was the 3rd largest land mammal known to live -- larger than modern elephants.

I've obviously used something of the skin texture of an Indian elephant here. I often dislike it when artists draw too heavily from living animals when reconstructing extinct ones, but a bit of speckled skin maybe isn't too big a crime.
